Welcome!
I am so glad you’re here.

I’m Michelle Gielan, and my work explores how optimism and resilience shape the way we lead, work, and live.

I’ve spent my career exploring a question that feels increasingly timely and important:


How do we stay clear-headed, resilient, and hopeful when the world feels heavy?

That curiosity led me to graduate study at the University of Pennsylvania, where I trained under Dr. Martin Seligman and began researching the science of happiness, optimism, and human potential. I wanted to understand how we can engage honestly with challenge while still strengthening motivation, agency, and the capacity for positive change.



What my research has revealed is clear: optimism isn’t soft—it’s strategic. When the brain is trained to focus on strengths, meaning, and possibility, stress decreases, creativity expands, and performance improves.



Over the past decade and a half, I’ve continued this work with leaders, parents, and organizations including Google, Meta, American Express, Boston Children’s Hospital, and Bank of America—helping teams build mindsets that support both well-being and success.



This work is also personal. In my twenties, I experienced a season of depression that taught me happiness isn’t about having perfect circumstances—it’s about how we interpret and respond to them. Learning to tell a different internal story became the foundation for both my research and my life.



Today, as a working mom married to fellow positive psychology researcher Shawn Achor, I’m reminded daily that optimism isn’t a fixed trait. It’s a practice—one shaped by what we pay attention to, what we amplify, and what we choose to pass on.



My mission is simple: to share science that helps people see what’s possible. Because every one of us is broadcasting something. And when that signal is grounded in resilience and optimism, it doesn’t just change us—it changes the people and systems around us.

Michelle Gielan has spent more than a decade and a half researching the link between happiness, optimism, and success. She is the bestselling author of Broadcasting Happiness: The Science of Igniting and Sustaining Positive Change and the author of the forthcoming book Resilient Optimism (Harvard Business Review Press), which explores how optimism becomes a measurable advantage under pressure.



Michelle is an Executive Producer of The Happiness Advantage on PBS and a featured professor in Oprah’s Happiness course. She formerly served as an anchor for The CBS Morning News, and her research and insights have been featured in dozens of media outlets, including The Washington Post, Forbes, and The New York Times.



She holds an advanced degree in positive psychology from the University of Pennsylvania and a B.S. in computer engineering from Tufts University.
